carbon dioxide on reaction gives a brisk effervescence. if you see the effervescence it's there because of carbon dioxide.
hydrogen gas burns with a pop sound. if a burning match stick is brought near the test tube it extinguishes with a pop sound.

Hi friend its really very easy to detect presence of carbon dioxide gas. For detecting the presence of hydrogen or co2
you need some metal like magnesium or zinc and hydrochloric acid for this reaction.
add metal to hydrochloric acid then the reaction will take place as follows and hydrogen will be evolved.
Mg + 2HCL -------> MgCl2 + H2(evolved)
Bring a burning matchstick above the test tube quickly
if you hear pop sound there is hydrogen gas but if the fire extinguishes then we can say that co2 is evolved.
